Physicist may have manipulated pure nothingness

I am really having trouble understanding this article.

What I do understand is that scientist may have found a way to not destroy a quantum system letting them get around Heisenberg uncertainty principle. After that I am a confused by pretty much the rest of the article.

Can someone explain the article? Also I really don't understand virtual particles. What are they? I think they are not real particles. Where do they go after disappear?



Please keep your answers simple because I am easily confused and don't know a lot about physics.

The title of the article is misleading. 'Pure nothingness' can't be manipulated because there's nothing to manipulate. The first thing the article does is say there's no such thing as total nothingness, which we knew anyway.

Everything is energy/matter. Forms come and go but energy remains. Energy can't be created or destroyed. Where there's energy there are bound to be forms. That's why there's no such thing as total nothingness. Nothing is still something and that can be manipulated, whatever that means.

Obviously an observer and the act of observation is bound to have an effect on the thing observed because the one isn't independent of the other. For observation to have zero influence on what it's observing it would have to be totally unrelated to the thing observed. Which it never can be.

An observer is not an observer if there's nothing to observe.
